An Overview of the Effects of Heavy Metals Content in Wastewater on Anammox Bacteria

Cherh Yih Mak, Jih-Gaw Lin and Mohammed JK Bashir

Abstract

The application of Anammox process in treating nitrogen rich wastewater had been more preferable since the discovery of Anammox process and Anammox bacteria at 1999 due to the advantages of energy saving and cost reduction compared to the conventional nitrification/denitrificationi process. However, often nitrogen-laden wastewater such as metal refinary wastewater, swine, industrial wastewater, and landfill leachate contain various concentrations of heavy metal ions such as Cadmium, Copper, Lead, Mercury, Nickel, Zinc, Silver and Ferrous iron.

Environmental Art and Environmental Beliefs: The Case of Plastic Bag Pollution in Oceans

Robert W Turner

Abstract

This paper reports the results of two experiments exploring the impact of exposure to environmental art on environmental beliefs, using images of plastic bag pollution in oceans. Even though the experimental design investigates only the immediate impact of a brief exposure to artistic images, the design controls well for other factors that might influence changes in environmental beliefs.

Temporal Variation of Nitrogen and Phosphorus Species Distribution on Total Phytoplankton Biomass in Eutrophic Lakes

Anusha Balangoda

Abstract

To aid in the eutrophication management, the relationships between total algal biomass in response to varying nitrogen and phosphorus species concentrations, Volatile (VSS), and Total Suspended (TSS) solids in the water column were investigated.

Landslide Effect on an Oribatid-Mite Community in a Monsoon Forest

Hao-Chiang Chien, Ping-Chun Lucy Hou, Haggai Wasserstrom and Yosef Steinberger

Abstract

Landslide-caused erosion of soil alters above ground plant cover and primary production, and is a major disturbance in forests and agro ecosystems in Taiwan. Bimonthly litter collections were conducted for one year, with oribatid mites studied at landslide sites and on the undisturbed forest floor.

Soil Ozonation for Nematode Disinfestation as an Alternative to Methyl Bromide and Nematicides

Nahed Msayleb, Ramesh Kanwar, Huaiqing Wu and J (Hans) van Leeuwen

Abstract

Phytoparasitic nematodes are important pests that cause severe crop yield losses. In the past, methyl bromide and other proprietary nematicides have been used as management practices, but these practices are unsustainable and lead to atmospheric pollution and ozone layer destruction.

Ozonation Efficacy in the Treatment of Soil-Borne Phytophthora sojae in Cultivating Soybeans

Nahed Msayleb, Ramesh Kanwar, Huaiqing Wu and J (Hans) van Leeuwen

Abstract

Ozonation was studied for inactivating Phytophthora sojae, a predominant soybean pathogen that causes root and stem rot, and pre-and post-emergence soybean damping-off. Typically, fungicides are used to treat soils to control the damage from P. sojae to soybean production.
